CHANNELING MACHINE.

SPECIFICATION forming part of Letters Patent No. 398,155, dated February 19, 1889.

Application filed July 31, 1888.

To all whom, it may concern:

Be it known that LWILLIAM HENRY HAVEN, J12, a citizen of the United States, residing at Oxford, in the county of Worcester and State of llilassachusetts, have invented new and useful Improvements in Channeling-Machines;

and I do hereby declare that the following, taken in connection with the accompanying drawings, is a specification.

Hy invention relates -to improvements in the construction and means of operating that class of machines generally known as the McKay bhanneling-Machines, and the ob jects of my invention are, first, to enable the operator to keep the sole, as it is propelled and moved by the feed-wheel and the presserwheel and as it is guided and turned by the operators hands, in a horizontal plane, and, second, in a mechanism to facilitate the driving and operating the machine by 1110- 1 'tive power.

I attain these objects by the mechanism illustrated in the accompanying drawings, in which Figure 1 is a vertical section of the ma chine, omitting parts of the mechanism not required to be shown for a clear defining of 5 my invention. 2 is a front elevation of upper part, Fig. 1. Fig. 3 is a top view of the planetable, the dotted lines showing the position of its snpporting-brackets beneath; Fig. 4, a front view of the plane-table; Fig. 5, a crossscction through the lines ac cc of Fig. 3; Fig. 6, a side view of the treadle; Fig. 7 a cross-section through the lines .2 e of Fig. 1..

Similar letters refer to similar parts throughout the several views.

A denotes the frame; B, the toothed feedwheel; 0, its shaft; D, a geared wheel fixed to the shaft, which engages with the geared wheel E, which revolves 011 a pin, a, attached to the frame; F, the presser-wheel attached to the shaft Z1, supported by the lever G. A geared wheel, cl, is attached to the shaft C, engaging with a geared wheel, 6, and communicates motion to the presser-wheel; H, the edge-wheel, or guide-roll. The arrangements of these parts, as also of the cutters, (not shown in the drawings,) are the same as in the McKay machine, and are old and in use. The part to which my improvement re- Serial No. 281,606. (No model.)

llates in this portion of the machine is the 5 addition and adaptation of a planetable, I, p which I attach to the frame A by means of the brackets j, in position that its upper surface is in. the plane of the upper edge of the feed-wheel and extending in front of it, I and surrounding the edge-wheel.

In operating the machine the sole is laid upon the plane-table, and as it is carried between the feed-wheels and the presser-wheel and against the edge-wheel, guided by the hands of the operator, it is retained by the plane-table in the requisite horizontal plane. Any deviation from the horizontal of the sole as it is carried against the cutting-knife and grooving-tool causes inequalities in the channel and groove cut,

To the geared wheel. E, I attach a belt-pub 3 hey, J, (in the place of the crank usually used).

g denotes a revolving shaft, to which is atiached a hub, K, having a conical surface, Z.

N denotes a hub movable on the shaft, having a conical surface, Z, fitting to the conical surface I, and a belt-pulley, L. The pulleys J and L are connected by abelt, '1'. By means of a bent lever, m, which is moved by a treadle, 'n, the operator can force the conical surface Z against the conical surface I, producing the friction required to give motion to the pulley L and bya belt to the pulley J It is important that the channel be commenced and ended at certain points on the sole, and that while a groove is also cut, it shall begin after and end before the channel; and to enable the operator to effect these results, and to perform the work expedt tiously, he must have the means to start and to stop the motion of the wheels suddenly.

It will be apparent that the operator, by a slight mo ement of the treadle, can quickly set the machine in motion and almost instantly stop it, and that it will be entirely under his control.

I am aware that prior to my invention a patent was granted to Wells & Bray, March 11, 1856, No. 14,426, for a shoe-sole machine which has a metal carriage whose outline is similar to the sole of a shoe, having geared teeth out in its circumference which engage with a pinion by which it is rotated upon a table. The sole is attached to this carriage and is carried under cutting-tools. This arrangement differs entirely in form, use, and position from my plane-tal'fle. The feed- WheeI, presser-wheel, and edge-Wheel of the McKay machine, which are parts of the combination of my claims, are notin the shoe-sole machine.

I am also aware that prior to my invention the arrangement of frictional cones operated by a treadle has been used for other purposes.

hat I claim as my invention, and desire to secure by Letters Patent, 1's

1. In a channeling-inachine, the combination of a feed-Wheel, B, a presser-wheel, F, and an edge-Wheel, H, with a plane-table, I, substantially as described.

2. The combination, in a channeling-machine, of a feed-Wheel, B, a presser-wheel, F, an edge-Wheel, H, With the hub K, having a conical surface, Z, and the hub N, with a conical surface, Z, for the purpose and substantially as set forth.
